In the gamepad object actions, you can specify getting values from the Left or Right Thumbstick.

So.

On Left Stick X < 0 -> move player left

On Right Stick X > 0 -> shoot right

Not The Thumbstick, I mean the whole 2 gamepads.

because I want to make a multiplayer game using twin usb gamepads(like the picture above).

I have to configure 2 gamepads at eventsheet, but how??

There are two ways handle more than 1 controller.

A. Every tick loop through each controller registered.

Check for each controller has state with loopindex

B. Provide an Event for each controller. You can set wich controller to check in the param for gamepad input.

I've tried the option B. But when I run the game on preview, the game still won't detect any gamepad input.

The event worked only for single gamepad?.

what should I do??
